Anthrax, gastrointestinal
- Gastrointestinal anthrax [1]
- Preferred regimen: Ciprofloxacin 400 mg intravenously every 8 h OR Doxycycline 100 mg intravenously every 12 h combined with second agent: Clindamycin 600 mg intravenously every 8 h or Penicillin G 4 MU every 4-6 hours OR Meropenem 1 gm intravenously every 6-8 hours or Rifampin 300 mg every 12 h.
- Note:Treatment for 60 days is recommended to avoid relapse or breakthrough of incubating disease. If initial therapy is intravenous, then convert to oral administration (Ciprofloxacin or Doxycycline) when clinically indicated. Steroids may be considered as an adjunct therapy for patients with severe edema and for meningitis. For pregnant women, avoid Doxycycline. Use Ciprofloxacin and switch to oral penicillin once susceptibilities are known.
Appendicitis
Biliary sepsis
Cholangitis
Cholecystitis
Diverticulitis
Esophagitis
Hepatic abscess
Hepatitis A
- The treatment should be conservative and supportive. There is no specific medication for HAV infection. Hygiene is very important, hands should always be washed after bathroom use. The management should focus on treating the symptoms and identifying the small proportion of patients with a particular risk of developing fulminant hepatic failure. Patients over the age of 40 and those with underlying chronic liver disease are most at risk.
- Contacts should be vaccinated.
- Oral contraceptive treatment and hormone replacement therapy should be stopped to avoid cholestasis.
- Alcohol consumption is not advised.
Hepatitis B
Management
- Spontaneous recovery occurs after acute infection with HBV occurs in 95-99% of previously healthy adults. Antiviral therapy is not therefore likely to improve the rate of recovery and is not required unless the disease is accompanied by a nonhepatic complication such as periarteritis nodosa. In such cases, and in immunocompromised individuals (e.g., those with chronic renal failure), antiviral therapy with lamivudine may be recommended.
- In fulminant hepatitis, meticulous intensive care may improve the survival, but orthotopic liver transplantation is the only therapy that has been shown to improve patient outcomes.
- Full recovery with development of anti-HBs provides long-term protection.
Prevention
- Vaccination (available since the early 1980s) continues to be the best way for dealing with the condition. Hepatitis B is preventable, and universal vaccination is probably best soloution in countries with a high prevalence.
- Preexposure vaccination:
- This is especially relevant in high-risk groups. There are a number of recombinant vaccines with similar efficacy, although the dosage may differ — for example:
- Recombivax HB (10 µg of HBsAg)
- Child < 11 y with an HbsAg-negative mother: 2.5 µg (babies at birth)
- Child < 11 y with an HBsAg-positive mother: 5 µg
- Child 11–19: 5 µg
- Immunocompetent adult: 10 µg
- Immunosuppressed person: 40 µg
- Renal dialysis patient: 40 µg
- Engerix-B (20 µg of HBsAg)
- Child < 10 y: 10 µg (babies at birth)
- Child > 10 y: 20 µg
- Adult: 20 µg
- Immunosuppressed person: 40 µg
- Dialysis patient: 40 µg 4.6.2
- Postexposure vaccination
